Does it have the magnets instead of snaps for the zipper sheild?
I scoured the web, but to no avail. However, if I were to take a stab at the answer, I would have to guess that it is likely snaps. I gander this is the case, because I believe that if the zipper shield had such a notable feature, it would be mentioned as part of the sell pitch.
If you are asking this question because it is likely you will purchase, you might try calling Billabong themselves, but the information you listed doesn't seem to produce any website hit with details regarding the zipper shield.
